Seasonal and interannual variability of primary and secondary productivity in a coastal fjord
Bibliographic record
Abstract
The phytoplankton and zooplankton dynamics in a coastal fjord in British Columbia were monitored in spring and early summer 2006 and 2007 to assess the annual variability in primary and secondary productivity and some characteristics of subsequent production. Phytoplankton biomass increased dramatically in early spring (spring bloom), declined abruptly, and then increased to a smaller peak two weeks after the spring bloom. Mesozooplankton biomass peaked one month after the spring bloom. The timing of the spring bloom was 20 days later in 2007. It is hypothesized that higher freshwater discharge and more frequent wind events in early spring 2007 were the driving factors behind the observed shift in bloom timing. The delay of the phytoplankton bloom resulted in a later and lower zooplankton biomass peak, and in a shift in zooplankton species composition. The implications of these changes for the survival of juvenile sockeye salmon are also discussed.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
